摘　　要：为利用开绕组永磁同步电机在双能量源间功率分配的灵活性,提出一种新型电动汽车动力系统构型,实现了从功率分配指令形成到指令跟随的过程。首先提出基于模糊控制的期望功率计算方法,使主能量源工作在高效区,并在电机控制层面基于双逆变器电压矢量模型,然后提出精确功率跟随、线性分配两种分配方法,实现主、次能量源期望功率的跟随。仿真结果表明:在电压矢量分配方法下,电机转速、转矩跟随效果良好,且转矩波动幅度限制在3 N·m以内。A new type of electric vehicle powertrain configuration was proposed in order to make use of the flexibility of open-winding permanent magnet synchronous motor in power distribution between dual energy sources,and realized the process from power distribution instruction formation to instruction following under this configuration.First,an expected power calculation method based on fuzzy control is proposed to make the main energy source work in high efficiency zone.Then,at the level of motor control,based on the voltage vector model of dual inverters,two distribution methods,namely precise power following and linear distribution,are proposed to realize the expected power following of primary and secondary energy sources.The simulation results show that under the voltage vector distribution method,the motor speed and torque follow well,and the torque fluctuation is limited within 3 N·m.
